  • Should I use aluminum sulfate (sulphate) to acidify my soil?

    4 Answers. Aluminum sulfate acidifies the soil because of the sulfate, not the aluminum. Actually, its possible aluminum, being Al+++, could take the place of 3 hydrogen ions (H+), though more likely is it would take the place of a Ca++ and 1 H+. Anyway, its the sulfate which causes acidity.
